[Solved] Wireless Network not connecting, think I missed..

Postby xendistar » 2018-08-11 15:01

I have installed Debian Buster on to a Lenovo laptop but I can not get the wifi working on, lspci shows the following:

Code: Select all
mit@Pyro:~$ lspci
00:00.0 Host bridge: Intel Corporation 3rd Gen Core processor DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09)

00:1f.3 SMBus: Intel Corporation 7 Series/C216 Chipset Family SMBus Controller (rev 04)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [NVS 5400M] (rev a1)
02:00.0 System peripheral: Ricoh Co Ltd MMC/SD Host Controller (rev 08)
02:00.3 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 PCIe IEEE 1394 Controller (rev 04)
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)


I believe the bottom line "Centrino Advanced-N 6205" is the Wifi adapter, I have installed "firmware-iwlwifi" which I beleive is the correct package for the centrino wifi

I have setup the wifi via the Network Manager

I can see that the iwl module has been loaded

Code: Select all
iwlwifi               225280  1 iwldvm

I did not want to paste the whole lsmod as it is quite large but if needed I can do

I tried #iwlist scan and it came back with my ssid (and a few of the neighbours) so it can see the ssid and the wifi network but won't connect to it

Can anybody confirm the bits I have done are correct and if so where do I go from here. I have had other linux distro installed on this laptop and the wifi has worked out of the box including one based on Debian Testing

If it was me I would try stable instead of testing. Buster isn't released yet. There could be a temp problem with some pkg or other?

If it's not working after following the wiki for firmware install
https://wiki.debian.org/iwlwifi
then I'd take a look in dmesg and make sure one of the firmwares is loading for the device. If you see the ssid in a scan or in nm, then I'd think the firmware is installed correctly.

If network-manager is giving you problems, there are other ways to connect on the link.
4. Configure your wireless interface as appropriate.

Thanks for the suggestion bw123, unfortunately it did not work (I added the line in network.conf) and did a complete reboot but it did not work. I then went back into Network Manager and removed all the settings for the wifi, rebooted the PC, went back into wifi and then re-entered them again the same as before and it worked. Not sure why but now I have wireless.

Thanks
